The mass of the man would remain the same…

His weight would change. Assuming the man’s weight on earth is 60 N.

Since weight is a force, according to Newton’s second law, F = ma ( m = mass, a = acceleration due to gravity)

First lets find the mass of the man, as it is required to find his weight on the moon.

F = ma [taking a of earth as 10 m/s^2]

60 = m . 10 [divide 10 on both sides]

m = 60/10 = 6 Kg

Acceleration due to gravity on the moon is 83% less than the acceleration due to gravity on earth (1.622 m/s^2).

F = ma

F = 6 . 1.622 = 9.732 N

So a person weighting 60 N on earth would approximately weight around 10 N on the moon.

Hope this helped!
